Can road barriers really prevent traffic accidents?

The road guardrail was initially designed to prevent vehicles and drivers from veering off the road when colliding with another vehicle or hitting obstacles on the road. So, can it really prevent traffic accidents?

First, let's speculate on what would happen if a vehicle hits the road guardrail.

1. It causes the vehicle to deflect, steering it back onto the road.

2. It brings the vehicle to a complete stop.

3. It slows down the vehicle, allowing it to pass just behind the guardrail.

In a head-on collision, the road guardrail absorbs the energy of the vehicle while colliding with the car. In the case of an angled collision, the guardrail bends and guides the following vehicles in a curved manner.

Road guardrails are built to absorb the force of cars and small SUVs. When a 60,000-pound truck collides with another vehicle at 60 miles per hour, it will directly crush it. Even at lower speeds, guardrails can actually cause injury and death. Although guardrails have limitations and are easily affected by the size and speed of vehicles, they still play a crucial role when the weight of the truck combined with the impact force causes the guardrail to function effectively, preventing more vehicles and more people from dying.

Therefore, it is still very necessary to install road guardrails on the roads. Although their capabilities are limited, they still do their utmost to protect the safety of pedestrians and vehicles, reducing the level of danger.
